Isaác Brizuela Muñoz (born 28 August 1990) is an American-born Mexican footballer who currently plays for C.D. Guadalajara in the Liga MX. Brizuela was born in the United States to Mexican parents, though he returned to Lagos de Moreno, Jalisco when he was two-years-old while his parents stayed working in California. He began playing football in his town until he was scouted to play for Toluca's youth squad in Guadalajara. Brizuela was promoted to the club's first-team squad in 2009 after good performances with the club's farm team, Atlético Mexiquense, from the second division. He also had a brief loan-spell with Club Atlas in 2013.
